Bearing cutting heat during cutting and cutting temperature

June 01, 2009, at 09:30 source: China's machine tool business cutting heat and temperature are imported bearing materials during cutting of another important physical phenomena. Increase of cutting temperature due to heat and thermal deformation of workpiece. direct effects of machining precision and surface quality of imported bearing materials. Temperature is the main factor affecting tool durability. Therefore, the study of cutting heat and temperature and variations have important practical significance.

Imports bearing material cutting hot of produced and outgoing, in tool of cutting role Xia, cutting layer metal occurred elastic deformation and plastic deformation, this is cutting hot of a source; while. in cut chip and Qian knife surface, artifacts and Hou knife surface between consumption of friction work also will into for heat? this is cutting hot of and a source. cutting hot by cut chip, and artifacts, and tool and around of media conduction out. According to thermodynamic equilibrium theory, generated equal heat of heat and mass transfer.
